Just wondering asking for a friend. At immigration in some countries they allow you to put the entry stamp in a separate sheet rather than on the passport. This is because the home countries do not allow travel to the incoming country. For example Saudis are not allowed to travel here. Does this happen here?
TLDR : Answer Summary
In Thailand, all entry stamps are placed inside your passport on the visa pages, and the practice of issuing a separate sheet for stamps, which is allowed in some countries, does not occur.
